Learning Outcomes (valid 01.08.2018-31.07.2020): 

2018-2019:

After attending the course successfully, the student is able to describe fundamental acoustic concepts such as sound pressure, particle velocity, speed of sound, characteristic impedance of the medium, radiation impedance, interpret the wave equation and Helmholtz Equation and their solutions under different conditions, interpret the behaviour of vibrational and acoustical systems,
apply analogies between the mechanical (acoustical) and electrical domains, and analyse wave propagation and sound radiation of simple sound sources, such as monopole, dipole, piston, and arrays.

2019-2020:

The student understands fundamental acoustic concepts and can interpret the wave equation and its solution under different conditions. The student also understands the behavior of simple vibrational and acoustical systems and is able to apply analogies between the mechanical (acoustical) and electrical domains. Finally, the student can analyze the wave propagation and sound radiation of simple sound sources.
